DETAILED DESCRIPTION

Memory loss is a serious problem that affects the lives of many people, and worsens as people age. Memory loss can be debilitating and prevent people from properly functioning in social and employment settings, disrupting work, hobbies, social activities, and family relationships. Memory loss and the inability to find objects can lead to depression and even result in life threatening situations.

Described embodiments provide techniques for automatically gathering information on tracked entities, comprising items or objects, a user has expressed an intent to memorize and the location of the tracked entities. Described embodiments utilize a gaze tracking device and a personal computing device to acquire a gazed image at which the user is gazing and classify speech received through a microphone of the personal computing device as having memorization intent. For user speech classified with memorization intent with respect to the gazed image, a tracking object is created to include the gazed image and an extracted description from the user speech of the tracked entity the gazed image represents. A determined location of the tracked entity of the gazed image may then be associated with the tracking object to allow tracking of the tracked entity to assist the user in memorizing and determining the location of the tracked entity.

FIG. 1 illustrates an embodiment of a personal computing device 100 configured for use to assist a user in determining a location of items or objects. The personal computing device 100 includes a processor 102, a main memory 104, a communication transceiver 106 to communicate (via wireless communication or a wired connection) with external devices, including a wearable gaze tracking device 108; a microphone 110 to receive as input sound external to the personal computing device 100; a display screen 112 to render display output to a user of the personal computing device 100; a speaker 114 to generate sound output to the user; input controls 116 such as buttons and other software or mechanical buttons, including a keyboard, to receive user input; and a global positioning system (GPS) module 118 to determine a GPS portions of the personal computing device. The components 102-118 may communicate over one or more bus interfaces 120.

The main memory 104 may include various program components including a natural language classifier 122 having a memorization intent classifier 124 to classify user received speech via the microphone 110 as having a memorization intent to memorize a location of a tracked entity; an entity recognition classifier 126 to classify in user received speech an entity that is the object of the memorization intent; a location classifier 128 to classify in user received speech a location of the object subject to memorization intent or a placement movement detected by the gaze tracking device 108; and a locator intent classifier 130 to classify user speech as a locator request to locate a tracked entity. The classifiers 124, 128, 128, 130 may use stemming and other language analysis techniques to classify and interpret the intent behind text of the user speech and return a corresponding classification with associated confidence levels. The classifiers may utilize language classification algorithms, such as the International Business Machines (IBM) Watson™ Natural Language Classifier. (IBM and Watson are trademarks of International Business Machines Corporation throughout the world).

The main memory 104 may further include an operating system 132 to manage the personal computing device 100 operations and interface with device components 102-120; a gaze tracker 134 to interface with the gaze tracking device 108 to receive a gazed image 140 detected by eye tracking cameras that acquire the gazed image 140 on which the tracked eye is fixed and proximate location images 142 within the field of vision captured by the gaze tracking device 108 cameras that are proximate to the gazed image the eye is tracking; a tracking object database 136 having information on tracked entities the user has expressed an intent to memorize and the location of the tracked entities; an image store 200 including images, such as stock images; and an image detection filter 138, utilizing algorithms for matching and recognizing images, to determine whether gazed and proximate location images from the gaze tracking device 108 match images in the tracking object database 136 and the image store 200. The tracking object database 136 may be implemented as a relational database, an object oriented database, and other types of databases.

A tracking manager 144 in the main memory 104 may manage the tracking related operations, such as managing the objects in the tracking object database 136 and managing the execution of other programs such as the natural language classifiers 122, image detection filter 138, and gaze tracker 134 to track entity location for the user.

The tracking object database 136 may include tracking objects 300, such as records or object oriented objects, having information on each tracked entity with which the user of the personal computing device 100 has expressed an intent to memorize; location objects 400, such as records or object oriented objections, having information on identified proximate location entities proximate to a tracked entity; a location history 500 providing associations of tracked objects and location objects to indicate locations at which a tracked entity was located; and tracking object alerts 600 having definitions of alerts to generate based on detected tracked entities and proximate location entities.

The personal computing device may comprise a smart phone, personal digital assistance (PDA), or stationary computing device capable of processing user information observed through the gaze tracking device 108. The memory 104 may comprise non-volatile and/or volatile memory types, such as a Flash Memory (NAND dies of flash memory cells), a non-volatile dual in-line memory module (NVDIMM), DIMM, Static Random Access Memory (SRAM), ferroelectric random-access memory (FeTRAM), Random Access Memory (RAM) drive, Dynamic RAM (DRAM), storage-class memory (SCM), Phase Change Memory (PCM), resistive random access memory (RRAM), spin transfer torque memory (STM-RAM), conductive bridging RAM (CBRAM), nanowire-based non-volatile memory, magnetoresistive random-access memory (MRAM), and other electrically erasable programmable read only memory (EEPROM) type devices, hard disk drives, removable memory/storage devices, etc.

The bus 120 represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnects (PCI) bus.

Generally, program modules, such as the program components 122, 124, 126, 128, 130, 132, 134, 138, 144 may comprise routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. The program modules may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices.

The program components and hardware devices of the personal computing device 100 of FIG. 1 may be implemented in one or more computer systems, where if they are implemented in multiple computer systems, then the computer systems may communicate over a network.

The program components 122, 124, 126, 128, 130, 132, 134, 138, 144 may be accessed by the processor 102 from the memory 104 to execute. Alternatively, some or all of the program components 122, 124, 126, 128, 130, 132, 134, 138, 144 may be implemented in separate hardware devices, such as Application Specific Integrated Circuit (ASIC) hardware devices.

The functions described as performed by the program components 122, 124, 126, 128, 130, 132, 134, 138, 144 may be implemented as program code in fewer program modules than shown or implemented as program code throughout a greater number of program modules than shown.

In alternative embodiments, the components of the personal computing device 100 may be embedded in the gaze tracking device 108.

FIG. 2 illustrates an embodiment of an image entry 200 _(i) in the image store 200 including an image identifier (ID) 202; an image 204, such as a graphics file representing a still image or motion picture; and a text description 206 of the image 204.

FIG. 3 illustrates an embodiment of an instance of a tracking object 300 _(i) of the tracking objects 300 including a tracking object identifier (ID) 302; a tracked entity image 304, such as a graphics file representing a still image or motion picture, which may comprise the gazed image 140 acquired by the gaze tracking device 108; a tracked entity description 306 comprising a textual description of the image 304; a most frequent location object 308 comprising a location object 400 _(i) in a maximum number of entries for the tracking object 302 in the location history entries 500; and a most recent location object 310 comprising the location object 400 _(i) identifying a location at which the tracked entity of the associated tracking object 302 was last located.

FIG. 4 illustrates an embodiment of a location object 400 _(i) of the location objects 400 as including a location object ID 402; a location image 404, such as a graphics file representing a still image or motion picture of a location proximate image; a location description 406 comprising a textual description of the location image 404; and a geographical location 408 of the proximate location entity, such as a GPS location from the GPS module 118.

FIG. 5 illustrates an embodiment of a location history entry 500 _(i) in the location history 500 as including a tracking object 502 identifying a tracked entity and an associated location object 504 identifying a proximate location entity at the location of the tracked entity, and a time 506 at which the tracked entity and the proximate location entity were detected by the gaze tracking device 108.

FIG. 6 illustrates an embodiment of a trigger alert instance 600 _(i) in the trigger alerts 600 including an alert ID 602; a tracking object ID 604 of a tracking object subject to the alert 602; a trigger condition 606 comprising a condition with respect to the tracked entity represented by the tracking object 604 and/or a proximate location entity represented by the most recent location object 310, such that satisfaction of the condition 606 causes a specified action 608 to be performed.

For instance, detecting a tracked entity with respect to a specified proximate location entity at a specified time may trigger a warning or alert. An alert may be triggered when a tracked entity, represented by tracking object 604, such as a key, is located with respect to a forbidden proximate location entity, such as a lock, door, etc. Another example is when the tracked entity comprises a prohibited access item, such as a medicine, drugs, food, television, refrigerator, etc., that is detected as the object of a placement movement at a specified time at which use of those tracked entities by the user is prohibited. The alert 608 may remind the user of the potential prohibited action or notify a person or organization monitoring the user of the personal computing device 100 and gaze tracking device 108 for prohibited access to tracked entities. Other conditions 606 may specify that the prohibition is triggered when a certain prohibited proximate location entity is detected with the tracked entity.

The data structures in FIGS. 2-6 show various fields of information. In alternative embodiments, different fields of information may be provided than that described, such as additional fields of information, or certain described fields of information may not be included.

FIGS. 7a, 7b, and 7c illustrate an embodiment of operations performed by the program components, such as the natural language classifiers 122-130, gaze tracker 134, and image detection filter 138 to process user speech input via the microphone 110 received concurrently with gazed images 140 and proximate location images 142 received from the gaze tracking device 108. Control begins upon the gaze tracker 134 processing (at block 700) a gazed image 140 and proximate location image 142 received from the gaze tracking device 108 concurrently with accompanying user speech received at the microphone 110 within a predetermined time indicating substantially concurrent receipt. The gaze tracking device 108 or gaze tracker 134 may determine the gazed image 140 as a portion of an image recorded by the cameras of the gaze tracking device that is being gazed upon by the eyes of the user, which may be tracked by eye cameras of the gaze tracking device 108. The gaze tracking device 108 or gaze tracker 134 may further determine the proximate location image 142 as a portion of the image recorded by the cameras that comprises a proximate location image of an entity or item located proximate with respect to the item comprising the gazed image 140. There may be one or more proximate location images 142 discerned from the recorded image.

In one embodiment, the gazed image 140 may comprise a tracking entity the user wants to memorize, such as car or house keys, television remote, smartphone, medication, etc., and the proximate location image 142 may comprise an item or entity proximate to the location of the gazed image 140 to track that is within the view captured by the gaze tracking device 108, such as a table top, desk, drawer, medicine cabinet or any other item that assists in identifying the proximate location of the gazed image 140 comprising a tracked entity to track.

The received user speech may be converted into text in order for the natural language classifier 122 components to perform the language classification analysis on the text of the user speech. The memorization intent classifier 124 processes (at block 702) the received user speech to determine whether the speech has memorization intent with respect to a tracked entity that is an object of the memorization intent. If (at block 704) the user speech is classified as having memorization intent, which is a desire by the user of the personal computing device 100 and gaze tracking device 108 to track an entity or item, then the entity recognition classifier 126 extracts (at block 706) from the received user speech a description of a tracked entity that is an object of the memorization intent.

If (at block 708) the image detection filter 138 determines that there is no location object 400 _(i) having a location image 404 matching the received proximate location image 142, then the tacking manager 144 creates (at block 710) a location object 400 _(C) including the proximate location image 142 as the location image 402 and a geographical location 408 of the personal computing device as determined by the GPS module 118. If (at block 712) the location classifier 128 determines that the user speech is classified to include a proximate location entity, then the tracking manager 144 adds (at block 714) to the created location object 400 _(C) a location description 406 of the proximate location entity extracted from the user speech. If (at block 712) the user speech is not classified to include a proximate location entity, then the image detection filter 138 determines (at block 716) whether the image store 200 includes an image entry 200 _(i) with an image 204 matching the proximate location image 142. If the image store 200 has the matching image, then the tracking manager 144 adds (at block 718) to the created location object 400 c the image description 206 as the location description 406.

If (at block 708) there is an existing a location object 400 _(i) in the location objects 400, then the tracking manager 144 determines (at block 720) the location object 400 _(i) having the location image 404 matching the proximate location image 142. After determining an existing or created location object at blocks 714, 716, 718 or 720, control proceeds to block 730 in FIG. 7 b.

At block 730, the tracking manager 144 determines whether there is a tracking object 300 _(i) in the tracking object database 136 having a tracked entity description 306 matching the extracted description of the tracked entity from the user speech and/or tracked entity image 304 matching the gazed image 140. If (at block 730) there is no existing tracking object 300 _(i) for the gazed image 140, then the tracking manager 144 creates (at block 732) a tracking object 300 _(C) in the tracking object database 136 including the gazed image 140 and the extracted description of the tracked entity as the tracked entity image 304 and the tracked entity description 306, respectively. After creating a tracking object 300 _(C) (from block 732) or if there is already a matching tracking object 300 _(i) for the gazed image 140 (from the yes branch of block 730), the tracking manager 144 adds (at block 734) an entry 500 _(i) to the location history 500 associating the determined/created tracking object 300 _(i) as tracking object 502 and the determined/created location object 400 _(i) as location object 504, and a time 506 at which the gazed image 140 and proximate location image 142 were captured by the gaze tracking device 108.

The tracking manager 144 may determine (at block 736) the most frequent location object 308 as the location object 400 _(i) in the maximum number of entries 500 _(i) for the determined/created tracking object 300 _(i) in the location history 500. The determined or created location object 400 _(i) may be indicated (at block 738) as the most recent location object 310 for the tracking object. The tracking manager 144 may then output to the user (at block 740) a description in text, image or voice format of the tracking entity and the proximate location entity to facilitate long term memory retention for the user of the location of the tracking entity, or gazed image 140. Text and images may be outputted to the display screen 112 or transmitted via text or message and voice may be outputted through the speaker 114.

If (at block 704) in FIG. 7a the user speech is not classified has having memorization intent, then control proceeds to block 750 in FIG. 7c . At block 750, the locator intent classifier 130 processes and classifies the received user speech to determine whether the speech has locator intent with respect to a tracked entity that is an object of the locator intent. If so (at block 752), then the entity recognition classifier 126 extracts (at block 754) from the user speech a description of a tracked entity that is an object of the locator intent, i.e., something the user wants to locate. If (at block 756) there is a matching tracking object 300 _(i) in the tracking object database 136 having a tracked entity description 306 matching the extracted description of the tracked entity, then the tracking manager 144 determines (at block 758) the location object 400 _(i) associated with the determined tracking object 300 _(i) having a geographical location 408 proximate to a geographical location of the personal computing device 100 as determined through the GPS module 118. The determined location object 400 _(i) may comprise the location object 504 in a location history entry 500 _(i) having a most current time 506 that has a geographical location 408 proximate to the user's current GPS location, where proximate means within a predefined distance. The tracking manager 144 may then output to the user (at block 760) a description in text, image or voice format of a location description 406 of a location included in the determined location object 400 _(i) as the location of the requested entity as a response to the location request determined by the locator intent classifier 130. Text and images may be outputted to the display screen 112 or transmitted via text or message, and voice may be outputted through the speaker 114.

If (at block 752) the user speech does not have locator intent, then the tracking manager 144 returns (at block 762) a notification via voice or text to the user that the request was not understood and to retry.

The described operations of FIGS. 7a, 7b, and 7c provide database related operations to determine whether received user speech can be classified as having memorization intent or locator intent to determine actions to take with respect to the database 136, such as adding tracking objects, location objects, location history entries, and outputting memorization intent or a location of a requested tracking entity to facilitate memory retention of the location of an object or entity of interest to the user.

FIG. 8 illustrates an embodiment of operations performed by the personal computing device 100 components to process a detected placement movement from the gaze tracking device 108 with respect to a tracked entity identified by one of the tracking objects 300 _(i) in the tracking object database 136. Upon the gaze tracker 134 detecting (at block 800) a placement movement by the user from the gaze tracking device 108 including a placed gazed image 140 and proximate location image 142, the tracking manager 144 determines (at block 802) whether there is a matching tracking object 300 _(i) in the tracking object database 136 having a tracked entity image 304 matching the placed gazed image 140. If so, then the operations at blocks 708-720 in FIG. 7a are performed to create or determine a location object 400 _(i) for the proximate location image 142. The tracking manager 144, and/or other components, performs (at block 806) the operations at blocks 734-740 in FIG. 7b to add an entry 500 _(i) to the location history 500 for the determined/created location object 400 _(i), updates the most frequent location object 308 and most recent location object 310, and outputs to the user a description of the tracked entity and the location of the tracked entity to facilitate long term memory retention.

If (at block 808) there is a trigger alert 600 _(i) associated with the determined tracking object 300 _(i), such as the trigger alert 600 _(i) including the determined tracking object 300 _(i) in field 604, then the tracking manager 144 determines (at block 810) whether a trigger condition 606 of the trigger alert 600 _(i), is satisfied. The trigger condition 606 may specify prohibited access of the tracked entity, which may be defined as the detected proximate location entity as proximate with a prohibited proximate location in the condition 606, or a prohibited proximate location within a time range.

If (at block 810) the trigger condition is satisfied, then the alert action 608 is performed, which may involve notifying the user via the microphone, text or email, or voice of the nature of the triggered alert, or notifying a monitoring agent at remote location. If (at block 810) the trigger condition is not satisfied or if (at block 808) there is no trigger alert associated with the determined tracking object, then control ends.

If (at block 802) there is no matching tracking object, indicating that the gazed image does not comprise an entity or item the user is tracking for memorization purposes, then control ends.

With the operations of FIG. 8, the tracking object for a tracked entity subject to a detected placement movement may be updated with a new location object indicating a new location of the tracked entity to provide accurate location information. Further, the detected placement movement may be analyzed to determine whether any trigger conditions are satisfied indicating perhaps a prohibited action with respect to the placed tracked entity and its new location that warrants a trigger alert to the user or other monitoring agent.
